Sunmaster Dual Spectrum HPS Bulb

The Sunmaster 600W Dual Spectrum Grow Lamp is a high-performance high-pressure sodium (HPS) grow bulb designed for both vegetative and flowering stages of plant growth. Manufactured by Sunmaster, this dual-spectrum lamp produces a balanced mix of red and blue light, allowing growers to use one bulb throughout the entire growing cycle.

Designed for indoor horticulture and hydroponic systems, the lamp provides strong light intensity and reliable performance to support vigorous plant development.

What the Sunmaster Dual Spectrum Lamp Does

Unlike standard HPS bulbs that focus mainly on flowering, the Sunmaster Dual Spectrum lamp emits both red and blue wavelengths, making it suitable for vegetative growth as well as the flowering phase. This balanced spectrum allows growers to use the same bulb without switching between metal halide and HPS lamps.

With an output of around 90,000 lumens, the bulb delivers high levels of photosynthetically active radiation (PAR), helping plants convert light energy efficiently for strong growth and higher yields.
